The Royal Institution and Michael Faraday 4 ll. t. Ch. 11 ( had completed by 1826. With the exception of Chemical Manipulation, all of Fara- day's books had previously appeared in the periodical litera- ture or else were transcriptions of public lectures. Like many another text, it arose out of a course, this one given at the Royal Institution as William Jensen describes in his "Michael Fara- day and the Art and Science of Chemical Manipulation". Faraday had plans for a new edition of Chemical Manipulation and as a former bookbinder he prepared an interleaved copy that he annotated with new material. This copy is now the proud possession of Sydney Ross who describes his treasure in "The Chemical Manipulator". Ross is also the author of "Unpublished Letters of Faraday and Others to Edward Daniel Clarke", interesting examples of the minutiae, then as now, of scientific life. For chemists Faraday's crowning achievement was the enunciation of the law(s) of electrolysis, as described in John Stock's "The Pathway to the Laws of Electrolysis". The final paper, "From Electrochemical Equivalency to a Mole of Electrons: The Evolution of the Faraday" by Marcy Hamby Towns and Derek Davenport, was first presented at a Work- shop for Teachers held during the Great Lakes Regional Meeting of the American Chemical Society in Indianapolis in late May. It is directed more at teachers of chemistry than at historians of chemistry but it may serve to illustrate a firmly held belief that history is too important to be left entirely to the Yn Mhl rd historians.

  • Joule's Thermoscope and the Second Law of Thermodynamics
    JOULE’S THERMOSCOPE AND THE SECOND LAW OF THERMODYNAMICS Summary This paper describes an instrument devised by Joule in 1863 to detect the energy of moonlight. It is extraordinarily sensitive to heat and must convert heat into mechanical energy with high efficiency. But since the temperature rise caused by moonlight is only 10-4F, the Carnot theorem would give a maximum efficiency of 10-6. JOULE’S THERMOSCOPE SHOWS THAT THE CARNOT EFFICIENCY LIMIT, THE MOST COMMON EXPRESSION OF THE SECOND LAW OF THERMODYNAMICS, IS WRONG The thermoscope uses convection currents and involves an energy cycle at constant volume. These features form the basis of proposals I have made for the efficient conversion of solar energy into electricity that were placed on my website in March 2002, September 2002 and March 2003. Indeed Joule‟s thermoscope is identical to Figure 3 in the latter Simple Solar Engine. It is my view that heat from fossil fuels or from solar energy can be converted into mechanical energy or electricity with an efficiency of up to 100% using energy cycles at constant volume. I would be very grateful for any comments. [E-mail address: williams.a(AT)globalwarmingsolutions.co.uk] Joule’s Thermoscope and the Second Law of Thermodynamics In 1863 James Joule devised an instrument to detect the energy of moonlight1, 2. It was to settle an argument with an adversary John Tyndall over whether the moon was hot or cold. He described the thermoscope as “a sort of wind thermometer”3. I am grateful to the Museum of Science and Industry in Manchester for their efforts to track down the instrument but it does not survive nor is there any detailed drawing.

  • The Faraday Effect
    Faraday 1 The Faraday Effect Objective To observe the interaction of light and matter, as modified by the presence of a magnetic field, and to apply the classical theory of matter to the observations. You will measure the Verdet constant for several materials and obtain the value of e/m, the charge to mass ratio for the electron. Equipment Electromagnet (Atomic labs, 0028), magnet power supply (Cencocat. #79551, 50V-5A DC, 32 & 140 V AC, RU #00048664), gaussmeter (RFL Industries), High Intensity Tungsten Filament Lamp, three interference filters, volt-ammeter (DC), Nicol prisms (2), glass samples (extra dense flint (EDF), light flint (LF), Kigre), sample holder (PVC), HP 6235A Triple output power supply, HP 34401 Multimeter, Si photodiode detector. I. Introduction If any transparent solid or liquid is placed in a uniform magnetic field, and a beam of plane polarized light is passed through it in the direction parallel to the magnetic lines of force (through holes in the pole shoes of a strong electromagnet), it is found that the transmitted light is still plane polarized, but that the plane of polarization is rotated by an angle proportional to the field intensity. This "optical rotation" is called the Faraday rotation (or Farady effect) and differs in an important respect from a similar effect, called optical activity, occurring in sugar solutions. In a sugar solution, the optical rotation proceeds in the same direction, whichever way the light is directed. In particular, when a beam is reflected back through the solution it emerges with the same polarization as it entered before reflection.

But perhaps it is not so well known that he also made fundamental contributions to the electromagnetic theory of light. In 1845, just 170 years ago, Faraday discovered that a magnetic field influenced polarized light – a phenomenon known as the magneto-optical effect or Faraday effect. To be precise, he found that the plane of vibration of a beam of linearly polarized light incident on a piece of glass rotated when a magnetic field was applied in the direction of propagation of the beam. This was one of the first indications that electromagnetism and light were related. The following year, in May 1846, Faraday published the article Thoughts on Ray Vibrations, a prophetic publication in which he speculated that light could be a vibration of the electric and magnetic lines of force.

Zheludev1, 3, ∗ 1Optoelectronics Research Centre and Centre for Photonic Metamaterials, University of Southampton, Southampton SO17 1BJ, United Kingdom 2School of Electrical and Electronic Engineering, Nanyang Technological University, Singapore 639798 3The Photonics Institute and Centre for Disruptive Photonic Technologies, Nanyang Technological University, Singapore 637371 (Dated: October 15, 2018) We demonstrate resonant Faraday polarization rotation in plasmonic arrays of bimetallic nano- ring resonators consisting of Au and Ni sections. This metamaterial design allows to optimize the trade-off between the enhancement of magneto-optical effects and plasmonic dissipation. Although Ni sections correspond to as little as ∼ 6% of the total surface of the metamaterial, the resulting magneto-optically induced polarization rotation is equal to that of a continuous film. Such bimetallic metamaterials can be used in compact magnetic sensors, active plasmonic components and integrated photonic circuits. The ability to tailor light-matter interactions is equally important for the development of current and future tech- nologies (telecommunications, sensing, data storage), as well as for the study of the fundamental properties of matter (spectroscopy). A typical example involves the exploitation of magneto-optical (MO) effects, where quasistatic mag- netic fields can induce optical anisotropy in a material. This is a direct manifestation of the Zeeman effect, the splitting of electronic energy levels due to interactions between magnetic fields and the magnetic dipole moment associated with the orbital and spin angular momentum [1]. This energy splitting gives rise to numerous polarization phenomena, such as magnetically-induced birefringence and dichroism, which enable dynamic control over the polarization state of light.

  • Faraday Rotation Measurement Using a Lock-In Amplifier Sidney Malak, Itsuko S
    Faraday rotation measurement using a lock-in amplifier Sidney Malak, Itsuko S. Suzuki, and Masatsugu Sei Suzuki Department of Physics, State University of New York at Binghamton (Date: May 14, 2011) Abstract: This experiment is designed to measure the Verdet constant v through Faraday effect rotation of a polarized laser beam as it passes through different mediums, flint Glass and water, parallel to the magnetic field B. As the B varies, the plane of polarization rotates and the transmitted beam intensity is observed. The angle through which it rotates is proportional to B and the proportionality constant is the Verdet constant times the optical path length. The optical rotation of the polarized light can be understood circular birefringence, the existence of different indices of refraction for the left-circularly and right-circularly polarized light components. The linearly polarized light is equivalent to a combination of the right- and left circularly polarized components. Each component is affected differently by the applied magnetic field and traverse the system with a different velocity, since the refractive index is different for the two components. The end result consists of left- and right-circular components that are out of phase and whose superposition, upon emerging from the Faraday rotation, is linearly polarized light with its plane of polarization rotated relative to its original orientation. ________________________________________________________________________ Michael Faraday, FRS (22 September 1791 – 25 August 1867) was an English chemist and physicist (or natural philosopher, in the terminology of the time) who contributed to the fields of electromagnetism and electrochemistry.

  • Notes on Corona-Resistant Antennas for High-Voltage Sensing Applications
    Notes on Corona-Resistant Antennas for High-Voltage Sensing Applications Prof. Gregory D. Durgin, Marcin Morys August 13, 2018 1 Introduction Within emerging smart grid technologies, there is a gaping hole in scientific knowledge regarding design, modeling, and characterization of radio antennas in high-voltage environments. Specifically, useful quantitative models do not exist for describing the dynamic physics of high-voltage AC corona plasmas and their influence on radiating structures; as a result, little guidance is available for the design and measurement of communication antennas that resist this phenomenon. It has long been understood that high-voltages produce severe compatibility and noise issues for radio communications [Juh08]. Only recently, however, has the effect of corona shielding been measured and shown to impair UHF and microwave communication devices that operate at high- voltage line potentials [Val10]. Valenta, et. al. measured a 10 dB drop in the 5.8 GHz received power from an antenna operating at 100 kV line-to-ground AC potential [Val10]. This drop in received power was due to the surrounding corona plasma, an invisible Faraday cage that reflects and attenuates radio signals as well as de-tunes and distorts the antenna that it encapsulates. Antenna designs that resist this corona shielding are critical for wireless sensors that monitor and protect the national power grid. 2 Review of High-Voltage Corona In this section, we review the basic physics of AC corona plasmas and preliminary results on their influence on radio communications using line-potential antennas. 2.1 Plasma Effects on Communications The influence of plasmas on radio communications has been extensively studied for ionospheric propagation.

  • Lab on Faraday Rotation
    Faraday Rotation Tatsuya Akiba∗ Truman State University Department of Physics (Dated: March 6, 2019) This paper reports the results of analyzing the Faraday rotation effect of SF-59 glass subject to a magnetic field generated by current through a solenoid. We verify Malus' Law to determine the orientation of the first polarizer. We set the nominal angle at an optimal φ = 45◦ to make relative intensity measurements at various magnetic field strengths. The relative intensity is measured using a photo diode and a simple circuit that allows for voltage readout. The exact magnetic field strength generated by a current through a solenoid of finite length is calculated and used to compute magnetic field strengths at various currents. A plot of the magnetic field strength integrated over the length of the optical material against the Faraday rotation angle is produced and a linear fit is obtained. The experimental value of the Verdet constant was obtained from the slope of the linear fit, and compared to two theoretical values: one provided by the manufacturer and one predicted by the dispersion relation. I. INTRODUCTION of known polarization state through an optical material in a magnetic field to obtain an experimental value of Faraday rotation is a magneto-optic effect that causes the Verdet constant. The magnetic field is generated by the polarization vector of light to rotate as it passes a solenoid, and we control the magnetic field strength by through an optical material in an external magnetic field controlling the current passing through the solenoid.
